The Energy Status display can be selected by pressing the ENERGY STATUS button. The following items and their present values will be displayed on the right side of the screen by pressing the up and down arrows.
AVERAGE PACKAGE kW HOURS − This displays the average package kW per hour for the time period that was started by selecting the reset averaging setpoint. This value includes the blower power usage.
AVERAGE % CAPACITY − Displays the compressor’s average percent capacity for the time period that was started by selecting the reset averaging setpoint. The value is determined by taking the average package kW per hour, removing the blower power usage and then dividing that number by the motor kW per hour for that size of compressor at 100% capacity.
AVERAGE CAPACITY − Displays the compressor’s average capacity in cfm or m3 for the time period that was started by selecting the reset averaging setpoint.
ENERGY COST − Displays the energy cost of the compressor for the time period that was started by selecting the reset averaging setpoint. This is calculated by multiplying the kW hours of the motor and the blower by the energy rate.
ENERGY SAVINGS − Displays the energy savings of the compressor for the time period that was started by selecting the reset averaging setpoint as compared to a conventional compressor. This value is determined by calculating how much a conventional compressor motor would cost to operate at the same average capacity and then subtracting the motor energy cost of the Nirvana compressor from it. It is assumed that the blower cost is the same in both packages.
LIFETIME ENERGY SAVINGS − Displays the lifetime energy savings of the compressor at the existing energy rate and at the average percent capacity as compared to a conventional compressor.
